Atenolol dissolution was unaffected by mixing crushed tablets with thin fluids or food mixers in comparison to whole tablets or crushed tablets in water, but amlodipine was delayed by mixing with jam. Mixing crushed warfarin and carbamazepine tablets with honey, jam or yoghurt caused them to resemble the slow dissolution of whole tablets rather than the faster dissolution of crushed tablets in water or orange juice. Crushing and mixing any of the four medications with thickened water caused a significant delay in dissolution. When tested with atenolol, all types of thickening agents at the greatest thickness significantly restricted dissolution, and products that are primarily based on xanthan gum also delayed dissolution at the intermediate thickness level.

Elevated circulating fatty acid-binding protein 4 (FABP4/A-FABP/aP2), an adipokine, is associated with obesity, insulin resistance, hypertension and cardiovascular events. However, how circulating FABP4 level is modified by pharmacological agents remains unclear. We here examined the effects of angiotensin II receptor blockers (ARBs) on serum FABP4 level. First, essential hypertensives were treated with ARBs: candesartan (8 mg day(-1); n=7) for 2 weeks, olmesartan (20 mg day(-1); n=9) for 12 weeks, and valsartan (80 mg day(-1); n=94) or telmisartan (40 mg day(-1); n=91) for 8 weeks added to amlodipine (5 mg day(-1)). Treatment with ARBs significantly decreased blood pressure and serum FABP4 concentrations by 8-20% without significant changes in adiposity or lipid variables, though the M value determined by hyperinsulinemic-euglycemic glucose clamp, a sensitive index of insulin sensitivity, was significantly increased by candesartan. Next, alterations in FABP4 secretion from 3T3-L1 adipocytes were examined under several agents. Lipolytic stimulation of the β-adrenoceptor in 3T3-L1 adipocytes by isoproterenol increased FABP4 secretion, and conversely, insulin suppressed FABP4 secretion. However, treatment of 3T3-L1 adipocytes with angiotensin II or ARBs for 2 h had no effect on gene expression or secretion of FABP4 regardless of β-adrenoceptor stimulation. In conclusion, treatment with structurally different ARBs similarly decreases circulating FABP4 concentrations in hypertensive patients as a class effect of ARBs, which is not attributable to blockade of the angiotensin II receptor in adipocytes. Reduction of FABP4 levels by ARBs might be involved in suppression of cardiovascular events.

Cardiovascular diseases are the leading cause of death worldwide. Risk factors are rarely seen individually, and the 2 most common and most frequently associated risk factors are hypertension and dyslipidemia (DL). Studies conducted in different parts of the world uniquely point out insufficient efficacy of hypertension and DL treatment, which is reflected in blood pressure and low-density lipoprotein levels higher than target values. A reason of this therapeutic failure is the reduced adherence, which is mainly caused by multidrug therapy. A possible solution for this problem is the use of fixed combinations. The main advantages of amlodipine/atorvastatin fixed combination are synergistic effect of these 2 components, a single-dose treatment, high safety profile, and good tolerance.

We used the Lequesne questionnaire to examine patients with osteoarthritis (212 patients, control group receiving no calcium antagonists) and patients with cardiac arrhythmia and osteoarthritis (188 patients treated with various calcium antagonists). The answers of the questionnaires were transformed into the Lequesne scoring system quantifying the severity of the disease. The Lequesne score is a standardized questionnaire focused on osteoarthritis. It is a 24-scale questionary in which low scores indicate low functional activity.

A total of 125 elderly patients with PHPT were randomly assigned to two groups: 59 in the control group treated by Western medicine and 66 in the intervention group treated by Western medicine combined with CM treatment. Based on syndrome differentiation, the patients in the intervention group were further divided into subgroups of yang-qi deficiency and yin-qi deficiency. All subjects were treated with Western medicine of Amlodipine Besylate Tablets and Irbesartan Tablets (or Irbesartan and Hydrochlorothiazide Tablets), to decrease their systolic blood pressure (SBP) slowly to 125-135 mm Hg in 2-6 weeks. In the intervention group, Shiyiwei Shenqi Capsule was given additionally to the subgroup of yang-qi deficiency at the dosage of 3-5 capsules, thrice a day, while Dengzhan Shengmai Capsule was given additionally to the subgroup of yin-qi deficiency at the dosage of 2 capsules, 2-3 times per day. For all subjects, SBP, pulse pressure (PP), and DBP were measured before treatment and at the terminal of a 6-week treatment. For subjects in the intervention group, left ventricular ejection fraction (LVEF) was also recorded.

Diuretics play a pivotal role in the management of hypertension. A large experience has been accumulated with indapamide , a long-acting thiazide-like diuretic that lowers blood pressure (BP) primarily through its natriuretic diuretic effect. Some of its long-term antihypertensive efficacy may be due to calcium antagonist-like vasorelaxant activities. Indapamide has protecting effects in a variety of conditions associated with high cardiovascular risk, such as diabetes, left ventricular hypertrophy, nephropathy and stroke. It is highly effective in lowering BP, whether given alone or in combination. Indapamide is well tolerated and has the advantage of having no adverse impact on glucose and lipid metabolism. Today, thiazide-like diuretics are regarded more and more as preferred drugs, when diuretic therapy is required to lower BP.

Although a relative weighting is difficult, it can be assumed that the combined effects of a polycythemia- associated hypercoagulability, an increased reagibility of the coronary arteries (aggravated by physical stress) as well as a hemoconcentration following prolonged exercise, could account for symptomatic recurrent minor thrombotic coronary events as well as the subtotal occlusion of the LAD. Obviously, this could not be prevented by a healthy lifestyle, regular physical activity, and the absence of classic coronary risk factors.

Pharmacokinetic interaction between benazepril (ACE inhibitor) and amlodipine (calcium channel blocker) was studied in 12 healthy subjects. Single doses of benazepril hydrochloride (10-mg tablet) and amlodipine besylate (tablet equivalent to 5 mg amlodipine) were administered alone or in combination according to a three-way, Latin-Square, randomized cross-over design. Serial blood samples were collected following each administration for the determination of benazepril and its active metabolite benazeprilat and amlodipine. The mean values of AUC (0-4 h), Cmax and Tmax for benazepril given as combination versus given alone were 161 vs 140 ng.h.ml-1, 168 vs 149 ng.ml-1, and 0.5 vs 0.6 h. The mean values of AUC (0-24 h), Cmax and Tmax for benazeprilat after benazepril given as combination versus given alone were 1470 vs 1410 ng.h.ml-1, 292 vs 257 ng.ml-1, and 1.7 vs 1.5 h. The mean values of AUC (0-144 h), Cmax and Tmax for amlodipine given as combination versus given alone were 118 vs 114 ng.h.ml-1, 2.5 vs 2.3 ng.ml-1, and 8.3 vs 9.0 h. The differences in these pharmacokinetic parameters between the combination and monotherapy treatments were not statistically significant based on ANOVA. The results of this study indicate that no pharmacokinetic interaction existed between the two drugs.

There are only minor differences in the pharmacokinetics of amlodipine between healthy subjects and hypertensive patients on haemodialysis. Comparison with literature values for healthy volunteers suggests that amlodipine is rapidly and extensively absorbed in the patient group. Amlodipine is essentially not dialysable. These findings do not indicate a need for dose adjustment in renal failure patients on haemodialysis.

The mean Hct was 41.8% (range 25.4% to 58.8%). Over 15 months of mean follow-up, there were 407 deaths (29 per 100 person-years). After adjustment for potential confounders, those in the lowest quintile of Hct (range 25.4% to 37.5%) had a 52% higher risk of death (hazard ratio 1.52, 95% confidence interval 1.11 to 2.10), compared with the highest quintile (range 46.1% to 58.8%). Within the lowest quintile of Hct, each 1% decrease in Hct was associated with an 11% higher risk of death (p < 0.01), whereas within the four higher quintiles of Hct, Hct was not associated with total mortality. Evaluation of different causes of death indicated that a lower Hct was strongly associated with death from progressive HF, rather than sudden death or other deaths.

It is known that calcium channel blockers induce Parkinsonism. In this study, amlodipine-, diltiazem-, and verapamil-induced catalepsy was investigated in mice. All of these three calcium channel blockers induced catalepsy. Dopamine D1, D2, and mACh receptor occupancies were estimated under the same conditions, and the affinities of these drugs for each receptor were also estimated in vitro. Intensity of catalepsy was predicted by dopamine D1, D2, and mACh receptor occupancies with the dynamic model which had already been constructed and was compared with the observed values. The predicted and the observed values were comparable (r = 0.98, p < 0.001). In conclusion, the dynamic model considering D1, and D2, and mACh receptor occupancy may be useful for quantitative prediction of drug-induced catalepsy.

We identified the factors associated with home blood pressure (BP) variability in 1933 patients treated with hypertensive drugs (mean age, 67 years; women, 55%). Multivariate regression analysis showed that female gender, advanced age, home BP value, and home heart rate variability were positively associated with home BP variability, whereas home heart rate, body mass index, and duration of antihypertensive treatment were negatively associated with home BP variability. Moreover, not being medicated with amlodipine and being medicated with angiotensin II receptor blockers were associated with increased home systolic BP variability only among patients who were treated for less than 12 months.

As part of the Amlodipine Cardiovascular Community Trial (ACCT), which was a large multicenter study designed to assess the effects of the calcium channel blocker amlodipine besylate (Norvasc) as monotherapy for treatment of mild to moderate hypertension, we sought to determine the effects of amlodipine on regression of left ventricular (LV) hypertrophy (LVH). The study began with a 2-week placebo run-in period (baseline), before which antihypertensive drugs had been discontinued. Amlodipine was then administered at 5-10 mg/day during a 4-week titration/efficacy period. Patients achieving a goal diastolic blood pressure (DBP) of < or = 90 mm Hg or a decrease in DBP of > or = 10 mm Hg entered a 12-week maintenance phase and had the option to continue long-term therapy thereafter. Echocardiograms were obtained in a subset of patients at the end of the baseline period. In patients with LVH at baseline, echocardiograms were repeated at the end of 16 weeks of therapy (week 18), and at 42 weeks in patients continuing long-term therapy. Thirty-seven percent of 124 hypertensive patients screened for LVH at baseline had LVH detected on echocardiograms. Blacks had a higher incidence of LVH (64%) as compared with whites (34%, p < 0.05). Patients with LVH were more likely to have a higher baseline systolic BP (SBP) and DBP. Their sitting SBP and DBP decreased significantly from a mean of 163/102 mm Hg at baseline to 139/86 mm Hg with amlodipine therapy at week 18 (p < 0.0001).(ABSTRACT TRUNCATED AT 250 WORDS)

Both patient- and physician-related factors have been shown to explain variability in the outcomes of antihypertensive treatment. Total cardiovascular risk (TCVR) is increasingly used as a determinant of treatment effectiveness but has also been proposed as a treatment outcome. To our knowledge, no studies have reported how antihypertensive treatment impacts blood pressure buy norvasc and TCVR outcomes.

Randomized, comparative study of 105 patients with mild essential hypertension, carried out at Shizuoka General Hospital. In phase 1, 40 hypertensives were allocated randomly into the losartan (50 mg) group or the quinapril (10 mg) group. In phase 2, 65 hypertensives, after 3 months 10 mg quinapril monotherapy, were allocated randomly into groups with 50 mg losartan (n = 32) or 5 mg amlodipine (n = 33) added to quinapril, and were treated for a further 3 months. All patients underwent [(123)I]metaiodobenzylguanidine (MIBG) imaging buy norvasc and neurohormonal measurements before and 3 months after treatment.

As recommended by the guidelines such as JSH 2004, combination therapy with multiple agents is now being applied to many patients with hypertension. However, a pharmacoeconomic analysis of each therapy has not been fully undertaken in Japan, despite increasing societal interest. In this study, the cost-effectiveness of two calcium channel blockers, each coadministered with an angiotensin receptor blockade, was compared using data from the ADVANCE-Combi study. The ADVANCE-Combi study was a 16-week double-blind, randomized clinical trial to compare the efficacy and safety of two combination therapies (controlled-release nifedipine [nifedipine CR] plus valsartan vs. amlodipine plus valsartan) on blood pressure (BP) control in patients with moderate to severe essential buy norvasc hypertension. The incremental cost effectiveness of each cohort was compared from the perspective of insurers. The average total cost per patient was Japanese yen (JPY) 31,615 for the nifedipine CR treatment group and JPY 35,399 for the amlodipine treatment group (p < 0.001). The achievement rate of the target BP (SBP/DBP < 130/85 mmHg for patients aged under 60 years; SBP/DBP < 140/90 mmHg for those aged 60 years and over) was significantly higher in the nifedipine CR treatment group (61.2%) than in the amlodipine treatment group (34.6%) (p < 0.001), with no difference in the incidence of drug-related adverse events. Accordingly, the base case economic analysis demonstrated that the nifedipine CR treatment group was dominant (more efficacious and less costly) to the amlodipine treatment group. This result was supported by univariate and probabilistic sensitivity analyses. These results indicate that nifedipine CR-based combination therapy is superior to amlodipine-based combination therapy for the management of essential hypertension in the Japanese population.

Male and female patients between 25 and 75 years-of-age with elevated diastolic blood pressure (four measurements > or = 95 mmHg from multiple measurements taken on three occasions and average diastolic blood pressure < 115 mmHg) were recruited from a population survey. After 4 weeks' placebo run-in, 71 patients were included of whom 60 finished the first study year and 51 finished the second study year. Patients were randomly assigned to receive doses of 5-10 mg amlodipine or 10-20 mg lisinopril, which buy norvasc were titrated on the basis of the effects on blood pressure. Primary endpoints were left ventricular mass index (LVMI) and early to atrial peak filling velocity. Office and ambulatory blood pressure were considered secondary endpoints.

Thirty-one lactating women receiving oral amlodipine once daily for pregnancy buy norvasc -induced hypertension were enrolled. Pre-dose plasma and milk concentrations of amlodipine were determined at day 6 or later after starting the medication. Relative infant dose (RID) as an infant risk for breastfeeding was calculated by dividing the infant dose via milk by the maternal dose.

Using a method combining lubrol-based extraction and subcellular fractionation on sucrose gradient, we found that amlodipine, but not verapamil or nifedipine, induced the segregation of endothelial NO synthase (eNOS) from caveolin-enriched low-density membranes (8+/-2% vs. 42+/-3% in untreated condition; P<0.01). We then performed co-immunoprecipitation experiments and found that amlodipine dose-dependently disrupted the caveolin/eNOS interaction contrary to other calcium channel blockers, and potentiated the stimulation of NO production by agonists such as bradykinin buy norvasc and vascular endothelial growth factor (VEGF) (+138+/-28% and +183+/-27% over values obtained with the agonist alone, respectively; P<0.01). Interestingly, we also documented that the dissociation of the caveolin/eNOS heterocomplex induced by amlodipine was not mediated by the traditional calcium-dependent calmodulin binding to eNOS and that recombinant caveolin expression could compete with the stimulatory effects of amlodipine on eNOS activity. Finally, we showed that the amlodipine-triggered, caveolin-dependent mechanism of eNOS activation was independent of other pleiotropic effects of the CCB such as superoxide anion scavenging and angiotensin-converting enzyme (ACE) inhibition.

SHR/ND were treated with vehicle (nU10), cilnidipine [33 mg/kg per day, orally (p.o.); nU11] or amlodipine (20 mg/kg per day, p.o.; nU9) for 20 weeks. SHR/ND developed proteinuria buy norvasc in an age-dependent manner. Cilnidipine suppressed the proteinuria greater than amlodipine did. The immunohistochemical analysis showed that N-type calcium channel and Wilm's tumor factor, a marker of podocyte, were co-expressed. SHR/ND had significantly greater desmin staining, an indicator of podocyte injury, with lower podocin and nephrin expression in the glomeruli than Wistar-Kyoto rat or SHR. Cilnidipine significantly prevented the increase in desmin staining and restored the glomerular podocin and nephrin expression compared with amlodipine. Cilnidipine also prevented the increase in renal angiotensin II content, the expression and membrane translocation of NADPH oxidase subunits and dihydroethidium staining in SHR/ND. In contrast, amlodipine failed to change these renal parameters.

1. Calcium channel blockers (CCBs) are anti-hypertensive drugs that are usually considered to act mainly as vasodilators. We investigated the relation between the reduction of blood pressure evoked by two long-acting CCBs and their protective effect against cardiac and renal damage in salt-loaded stroke-prone spontaneously hypertensive rats (SHRSP). 2. SHRSP were exposed to high dietary salt intake (1% NaCl in drinking solution) from 8 to 14 weeks of age, with or without amlodipine or lacidipine at three dosage regimens producing similar effects on blood pressure. 3. The lowest dosages of both drugs had non-significant effects on blood pressure but inhibited the paradoxical increases in plasma renin activity (PRA) and in renin mRNA in kidney that were found in salt-loaded SHRSP. The lowest dosage of lacidipine (but not of amlodipine) restored the physiological downregulation of renin production by high salt and reduced left ventricular hypertrophy and mRNA levels of atrial natriuretic factor and transforming growth factor-beta1. 4. The intermediate dosages reduced blood pressure and PRA in a comparable manner, but cardiac hypertrophy was more reduced by lacidipine than by amlodipine. 5. Although the highest doses exhibited buy norvasc a further action on blood pressure, they had no additional effect on cardiac hypertrophy, and they increased PRA and kidney levels of renin mRNA even more than in the absence of drug treatment. 6. We conclude that reduction of blood pressure is not the sole mechanism involved in the prevention of cardiac remodelling by CCBs, and that protection against kidney damage and excessive renin production by low and intermediate dosages of these drugs contributes to their beneficial cardiovascular effects.

This post hoc analysis from the Sevikar Compared to the Combination of Perindopril Plus Amlodipine on Central Arterial Blood Pressure in Patients With Moderate-to-Severe Hypertension (SEVITENSION) study assessed the efficacy and tolerability of olmesartan (OLM) and amlodipine (AML) in reducing central systolic blood pressure (CSBP) compared with perindopril (PER) plus AML in hypertensive patients with type 2 diabetes. Patients were randomized to OLM/AML 40/10 mg or PER/AML 8/10 mg for 24 weeks. The primary Mobic 15mg Tablets efficacy endpoint was the absolute change in CSBP from baseline to week 24, which was greater with OLM/AML (-13.72±1.14 mm Hg) compared with PER/AML (-10.21±1.11 mm Hg). The between-group difference was -3.51±1.60 mm Hg (95% confidence interval, -6.66 to -0.36 mm Hg) and was within the noninferiority margin (2 mm Hg) as well as the superiority margin (0 mm Hg). In addition, OLM/AML was associated with a higher proportion of patients achieving blood pressure normalization. In hypertensive patients with diabetes, the fixed-dose combination of OLM/AML was superior to PER/AML in reducing CSBP, as well as other secondary endpoints.

The homeostatic control of arterial BP is well understood with changes in BP resulting from changes in cardiac output (CO) and/or total peripheral resistance (TPR). A Aricept Dose Time mechanism-based and quantitative analysis of drug effects on this interrelationship could provide a basis for the prediction of drug effects on BP. Hence, we aimed to develop a mechanism-based pharmacokinetic-pharmacodynamic (PKPD) model in rats that could be used to characterize the effects of cardiovascular drugs with different mechanisms of action (MoA) on the interrelationship between BP, CO and TPR.

The pupil is a suitable end organ for studying autonomic function because both sympathetic and parasympathetic nerve activity can be evaluated independently using a light stimulus. Sympathetic response elicited by physical stress is augmented in hypertensive patients compared with normotensive subjects, which increases the risk of cardiovascular events. We used pupillometry to evaluate the effects of the calcium channel blockers azelnidipine (AZ) and amlodipine (AM) on changes in autonomic nervous activity induced by isometric exercise in patients with hypertension. Twenty patients with essential hypertension who were administered AM and 21 who were administered AZ underwent a pupillary function test and blood pressure (BP) Prednisone Cost and pulse rate (PR) measurements before and after isometric handgrip exercise (IHG). Maximal velocities of pupil constriction (VC) and re-dilation (VD) obtained with light stimulation for 1 s were used as indices of parasympathetic and sympathetic nerve activity, respectively. Increases in systolic BP and PR elicited by IHG were significantly smaller in the AZ group than in the AM group. After IHG, both VC and VD significantly increased in the AM group but not in the AZ group. The low-to-high frequency ratio obtained from analysis of PR variability, another measure of sympathetic activity, also increased in only the AM group. Thus AZ inhibited autonomic activation and suppressed cardiovascular responses to IHG more effectively than AM. The sympathoinhibitory effect of AZ may therefore be beneficial for patients with essential hypertension. In addition, pupillometry was shown to be a useful tool for assessing autonomic function in hypertensive patients.

Combined treatment of statins and calcium channel blockers has been suggested to be superior to statin therapy alone. We quantified the anti-atherosclerotic potential of amlodipine, atorvastatin and their combination on existing atherosclerotic plaques in the aorta of APOE*3-Leiden transgenic mice. Sixty-two mice were fed a high cholesterol containing diet for 18 weeks. A subgroup of 10 mice was then killed. All other mice received the diet for another 18 weeks, alone (late control group), along with 0.01% atorvastatin, 0.002% w/w amlodipine, or their combination (all groups, n = 13 Flagyl Iv Dose ). Atherosclerotic lesions, collagen content and monocyte adherence were quantified using standard histology (aortic root). Raman spectroscopy was used to quantify the content of cholesterol and calcification (aortic arch). Compared to the late control group, treatment with amlodipine, atorvastatin or the combination, reduced atherosclerostic lesion area by, respectively, 25%, 39% and 46% in the aortic root (P < 0.01) and by 53%, 55% and 60% in the aortic arch (P < 0.05). Atorvastatin, but not amlodipine reduced the adherence of monocytes in the intima. Lesion severity and plaque contents of collagen, cholesterol and calcification were equal for all treatment groups. Neither treatment resulted in regression of atherosclerotic plaque size. In conclusion, both atorvastatin and amlodipine significantly retard the progression of existing atherosclerotic lesions. No additive effect of the combination of amlodipine and atorvastatin could be observed in this study.

Hypertensive kidney disease commonly progresses. The primary objective of the AASK ( Cymbalta Pharmacy Prices African American Study of Kidney Disease and Hypertension) Cohort Study is to determine prospectively the course of kidney function and risk factors for kidney disease progression in African Americans with hypertensive kidney disease who receive recommended anti-hypertensive therapy. The AASK Cohort Study is a prospective, observational study that is an extension of the AASK trial. The AASK trial tested the effects of three medications used as initial anti-hypertensive therapy (ramipril, metoprolol, and amlodipine) and two levels of BP control. Of the 1094 trial participants, approximately 650 to 700 individuals who have not reached ESRD will likely enroll in the Cohort Study. Risk factors to be studied include environmental, genetic, physiologic, and socioeconomic variables. The primary renal outcome is a composite clinical outcome defined by doubling of serum creatinine, ESRD, or death. Medication treatment for hypertension, beginning with the angiotensin converting enzyme inhibitor ramipril, is offered to all participants. In this fashion, the study directly controls two of the major determinants of kidney disease progression: treatment of hypertension and use of renoprotective, anti-hypertensive medication. The minimum duration of follow-up in the Cohort Study is 5 yr (total of 9 to 12 yr, including the period of the AASK trial). Ultimately, data from the AASK Cohort Study should enhance our understanding of the risk factors and processes that determine the progression of kidney disease. Such results might eventually lead to new strategies that delay or prevent ESRD.

It has been assessed in terms of physical stability and pharmacokinetic and pharmacodynamic properties and been found to be effective in lowering blood pressure in preclinical and Phase I and II trials. However, to date, no studies have compared the clinical effectiveness of amlodipine camsylate and amlodipine besylate in treating hypertension.

A novel 96-microwell-based spectrophotometric assay has been developed and validated for determination of olmesartan medoxomil (OLM) in tablets. The formation of a colored charge-transfer (CT) complex between OLM as a n-electron donor and 2, 5-dichloro-3, 6-dihydroxy-1, 4-benzoquinone (p-chloranilic acid, pCA) as a π-electron acceptor was investigated, for the first time, and employed as a basis in the development of the proposed assay. The proposed assay was carried out in 96-microwell plates. The absorbance of the colored-CT complex was measured at 490 nm by microwell-plate absorbance reader. The optimum conditions of the reaction and the analytical procedures of the assay were established. Under the optimum conditions, linear relationship with good correlation coefficient was found between the absorbance and the concentration of OLM in the range of 1-200 μg ml-1. The limits of detection and quantitation were 0.3 and 1 μg ml-1, respectively. No interference was observed from the additives that are present in the pharmaceutical formulation or from hydrochlorothiazide and amlodipine that are co-formulated with OLM in some formulations. The assay was successfully applied to the analysis of OLM in tablets with good accuracy and precision. The assay described herein has great practical value in the routine analysis of OLM in quality control laboratories, as it has high throughput property, consumes minimum volume of organic solvent thus it offers the reduction in the exposures of the analysts to the toxic effects of organic solvents, and reduction in the analysis cost by 50-fold. Although the proposed assay was validated for OLM, however, the same methodology could be used for any electron-donating analyte for which a CT reaction can be performed.
